Check Text ( C-52329r4_chk )
Check the syslog configuration file for mail.crit logging configuration. Depending on what system is used for log processing either /etc/syslog.conf or /etc/rsyslog.conf will be the logging configuration file. Procedure: # grep "mail\." /etc/syslog.conf Or: #grep "mail\." /etc/syslog.conf If syslog is not configured to log critical sendmail messages ("mail.crit" or "mail.*"), this is a finding.

Check the syslog configuration file for mail.crit logging configuration. Depending on what system is used for log processing either /etc/syslog.conf or /etc/rsyslog.conf will be the logging configuration file.

Procedure:

# grep "mail\." /etc/syslog.conf

Or:

#grep "mail\." /etc/syslog.conf

If syslog is not configured to log critical sendmail messages ("mail.crit" or "mail.*"), this is a finding.
